GNU Phantom.Security uses a simple electronic circuit that you build (the
circuit diagram is included, and can be completed by even a novice with minimal
electronics experience... or get a friend to do it :) ). The device
(Phantom.Controller) is connected to a parallel port on your computer. You
can connect security devices to Phantom.Controller such as door magnets, motion
sensors, and smoke detectors! You can usually use any off-the-shelf item with
a simple modification. Examples and sample setups are included in the GNU
Phantom.Security package. GNU Phantom.Security can be used in small home or
office settings or can be expanded into a large networked system!
